This invention relates to a vroad making machine andparticularly to sucha machme adapted to operate on concrete or cement"` roads; In makingconcrete roads 1t has heretofore been the practice to deposit-theconcrete. on the roadbed foundation and then to level oil' the layerofconcrete by screed bars or boards which are moved over the surface ofthe concrete layer. Thisprocedure takes considerable time and labor andthe resulting road surface is usually not uniform.

It is an object of this invention to provide means for forming thesurface ofthe concrete layer and `properly shaping the same comprising aroller which is moved over the said surface. n

It is a further,v object of the invention to provide a machinecomprising a frame supported upon trucks adapted to move along the roadat the side thereof., which frame com.

`prises members extending across the road and. forminor a uidin@r meansfor a roller which is s g e n reciprocated across theroad.

It isl a further object of the invention-t0l provide said frame memberswhich extendl across the road with means for guiding the vroller in a.non-rectilinear path whereby a crowned surface maybe.v given to theroad.

It still another object ofy the invention to provide such a machinehavinga bar extending across the road at the front thereof for` roughlyshapiner the surface, which bar, preferably is provi ed withreciprocating means. It is a still further object of the invention toprovide a machine having a frame adapted f to carry amotor together with.means driven from the motor for turning the truck wheels to progressthe machine, for reciprocating the 'said roller and for reciprocatingthe screed` bar at the front ofthe machine.

These and other objects and advantages of the invention will be fullyset forth inthe following description made in y connection with theaccompanying drawings in which like reference characters refer to theysame parts throughout t-he different views, and in which, h y y Fig. lisa plan view ofthe machine;

Fig. 6 is av vertical section taken on the line Referring to thedrawings, the machine comprises truck wheels 1 which are disposed ateach side of the road and which may travel on track members 2 providedtherefor. The said wheels are spacedlongitudinally of the road andjournaled in framesor brackets 3 having flat flanges at the top thereof,said brackets having depending bearing carrying arms between whichthewheels 1 revolve. The bearings 3 with ythe wheels at each side of theroad are connected byspaced` channel members 4 which are ybolted to thetop flanges of the brackets 3. I-beams 5 extend transversely of thechannels Lland beneath the same and are bolted thereto by boltsextending through the flanges of said channels. Thev I-beams 5 f extendtoward. each other from each side of the machine and a roller 6 restsupon the top of each of said I-beams which is carried on an axle 7supported in bearings Sand 8, The bearing 8 has. a flange extend-ingdownwardlry and adapted toA lie in flat contact with a larger channel 9to which it is secured by spaced bolts or rivets. 10. The bearing 8aextends downwardly at the other side vof the beam 5 and has a horizontalflange disposed under and connected to the upper flange of the channel9. The large channel 9 is fthus supported from the I-.bearn 5 and thereis one of the channels, QeXtending transversely between the respectivepairs of channels 4; at each end of the machine. The c-hannels 9 havebolted to the outside thereof, adjacent the bearings 8' one of theflanges ofthe angle. members 11 whichextend` upwardly. and have boltedto their other flanges., channel mem.- bers 12 which extend across thetop of I- beam 5, parallel to the channel members 4.

flanges bolted to the outside of the channels 9 above the bottom thereofand'extended outwardly and upwardlyadjacent the ends of y the channelmembers l2 to whichthe. horizontal flanges thereof are bolted orriveted. The

Channel members 12,y in, turn,` have' extending therebetween yandrestingk thereon channel members 14, the latter. members being secured,to the. members 12 any suitable manner.

The chan-nel members e have secured to `the inside theme15 adjacenttheir bottoms smaller channels 15 adapted to form guideways for rollermembers 16 journaled on stub shafts secured in block members 17 in thecentral portion of which are journaled trunnions 18 of a comparativelylarger roller 19 which extends between t-he blocks 17. The machine issimilar in construction at each end and each side and a description ofone of said ends and sides will be sufficient to under-v stand thestructure. Only a portion of one end therefore is shown in Fig. 3 andonly a portion of one side in Fig. 2, it being understood that thesestructures are duplicated at the other end and side of the machinerespectively. The blocks 17 have secured at each end thereof beyond therollers 16, the lends of a chain member 20, each end of which chainpasses from the block toward one end of the machine and passes over asprocket 21 secured to a shaft journaled in pairs of angle members 2-2extending across the top and downwardly beyond the channel members 4,v

to which they are secured. Between the Sprockets 21 the upper run of thechain 2O passes under sprockets 23 carried on short shafts mounted inbearings 24 secured to a short section of channel 25 rest-ing upon andsecured to the top of the channel member 9. Between the sprockets 23 thechain passes over a larger sprocket 26 secured to a shaft 27 which isjournaled in a bracket 28 secured to the member 25. It will beunderstood that there is a member 25 with its attached parts secured toeach of the members 9 and I' the shaft 27 extends between the members 9and the members 25 secured thereto. Seid shaft 27. has its end projectedbeyond the front member 9 and has secured to said end a worm Wheel gear30 driven by a worm gear secured at a shaft 31 which is, in turn, drivenby mechanism to be later described. It will be seen that if the wheels26-are driven the chain 20 will be progressed and the blocks 17 androller 19 moved in one direction or the other. The channel member 15 isconnected to the top web of the channel member 9 by a central bolt 32and bolts 33 at each side thereof, said bolts being provided with jambnuts at each side of each web of the channels. The central bolt 32 withthe nuts thereon is adapted to draw the central part of the channel 15upwardly, the end portions of said channel being held and forceddownwardl by the bolts 33 and the nuts thereon where y the channel isflexed and is given curved form with the central portion thereof hi herthan the end portions.

he wheels 1 are equipped with sprocket wheels 34 over which run chains35 also runnin over sprocket wheels 36 secured to the sha s 37 carriedin bearings 38 bolted to the top of the members 4 adjacent the endsthereof. The shafts 37 also carry sprockets 38 and chains 39 run overthese sprockets on the shafts at each end of the respective pairs ofchannels 4. The upper runs of the chains 39 are engaged by sprocketwheels 40, as illustrated in Figs. 1 and 3, one of which sprockets 40 iscarried on a shaft 41 and the other of which is carried on a shaft 42,which shafts project inwardly from the inside members 4 and have securedthereto, respectively, the gears 43 and 44. These gears are disposed onopposite sides of and mesh with another gear 45 carried upon a shaft 46.The frame members 14 are adapted to support a suitable motor 47 whichmay be of any suitable Vtype such as a steam engine, internal combustionmotor or electric motor. The motor 47 is illustrated an internalcombustion motor the driving shaft of which is shown as 48 and carriesthe usual fly wheel 49a; The shaft 48 drives another shaft 49 throughthe reducing gears 50 and 51, which shaft 49 is equipped with a pair ofoppositely facing beveled gears 52 meshing with a larger beveled gear53a on the shaft 31 to which reference has been made. The gears 52 aremounted to turnY loosely on the shaft 49 but are adapted to be connectedthereto by engagement with a sliding clutch member 53 controlled througha pivoted bell crank lever by the rod 54. By connecting one or the otherof the gears 52 with the clutch 53 the shaft 31 can be driven in eitherdirection and will, in turn, drive shaft 27 in either direction and moveroller 19 in one direction or the other between the sides of the frame.The shaft 48 also drives the shaft 55 through the gears 56 or 57 and theshaft 55, by means of the worm gear 58, drives the shaft 46 to which aworm wheel gear is secured meshing with the worm gear 56.

The channel members 12 are extended at the front of the machine and havebolted thereto parallel flanges extending' from plates 58, which plates58 extend transversely of the members 12. A screed blade comprisingportions 59 and 60 has members 61 secured to the rear thereof carryingbolts 62 passing through longitudinal slots in the plates 58, said boltsbeing slidable in said slots and heldin place by suitable nuts appliedthereto. The members 59 and 60 as clearly shown in Fig. 1, converge.toward the center of the machine where they meet in a very obtuse angleand at which portion they have secured thereto a member 63 having a bolt68 projecting therefrom through a horizontal Slot in a bracket 64 boltedto one of the members 9 and one of the auxiliary frame members 65. Ashaft 49 projects at one side of the auxiliary frame member 66 and has acrank disk 66a at said end connected by a suitable crank pin with apitman link 67 which is connected at its other end to the bolt 68projecting through brackets 64. The blades 59 and are, hence, given. alateral reciprocating motion and are guided in the brackets 58 and 64.As shown in Fig. 4, the bar or plate 60 is vertically adjustable on thebar yor plate `59, the latter being provided with slots 59a receivingheaded andi nutted bolts 60aL passing through the platel 69. The bottomedge of the plate 60 inclines upwardly toward` the center thereof, asclearly shown in Fig. 2.

At times, roads of eXtra width are made and itis a Ageneral practice tomake the road wider at curves. In making such extra wide portions it isdesirable to have extra travel given to the roller 19. The channelmembers 9, therefore, have bolted to the ends thereof junction plates 70adapted to have bolted thereto extension` channels 1 similar to thechannels 9. When the extension members 71 are used the wheels 1 andparts carried there by including the channel members 4 should be movedoutwardly and for this purpose the vI-beam 5 'isl provided on its lowerand outer web with a rack member 72 adapted to be engaged by a pinion 73 carried on a'shaft journaledr in a bearing 7 4El bolted to the outsideof the channel 9, which shaft is adapted to be turned. by a han-d crank74. There will, ofcourse, be a rack 72 and hand crank 74 for each of theIsbeams 5y and when the said hand cranks are turned the channelA members4, brackets 3 and attached parts will be moved .outwardlywi'th theI-beam the latter sliding on the topofchannels9A and being held inengagement therewith` by the yoke members 7 5 bolted to. said channelsand extending over the tops of I'beams 5. The end portions of the frameof themaehine are thus moved outwardly with the wheels 1 and the roller8 can thus be given a greater lateral travel. It will be understood thatthe extension section 71 of the channels 9 will also contain and havesecured' therein smaller channels 72 of the samel size as the channels15l and adapted to abut the ends thereof. f

In operation, the machine will be disposed vat the `proper place on theroad where the concrete layer'is being laid andi the machine can beprogressed by power from the rmotor.

47 transmitted through the shafts 41 and 42 which,i`n turn,l drives thechains 39. The

chains 39 drive the shafts 37' which, through sprockets 3G and chains 35turn the .wheels 1.` As the machine` moves forwardly after the layer ofconcrete has been placed on` the roadbed, said layerwill' be leveled offto aps proximately the right shape by thevplate or bar 60. This plate,as alreadyy described, is given a longitudinal' reciprocating movementtransversely of the road which will assist in properly surfacing orscreeding the concrete layerv and will relieve the resistance of theparticles of concrete to the movement of the machine. By thusprogressing the machine,

. the roller 19 is brought over the newly laidr conc-rete.

The rod 54y is now operated to move 'the clutch 'block 53 successivelyinto engagement with the gears 52 and the roller 19 is moved across theroad on top of the face ofthe road. The roller 19 rests lightly y uponthe concrete and as it is reciprocated over the same, securely packs andevens the surface thereof forcing the hard particles into the body ofthe concrete and permits the grout and cement to make the desired smoothsurface. After one section of the road is thus treated the machine will,of course,` be moved forwardly to the next section on which the concretehas been in the meantime deposited. i The actionof the machine is quiterapid yand the construction of the road can be speedily progressed.Where wider portions of the road are made, the extensions. 71 and 72will be bolted to the late 70 and the end frames. andwlieels at t e wideside of they road moved outwardly.- The roller 19 `can then betraversedover the eXtra width of the road, it being understood, of course, thatthe chain 20 will have to be lengthened.`

Whenthe layer of concrete has been placed on the roadbed, saidy layerwillrbe leveled off to approximatelythe right shape by the plate or bar60. As the arms of this plate diverge from the center the surplusconcrete in the ylayer will be moved away from the edges of the pavementand toward the. center thereof. The sur lus concrete will thus not bepushed over t e edges of the pavement where it will have to again becollected. Owing to the fact that the plate 60 is reciprocated, thesurplus concrete is struck off or leveledby a partial shearing actioninstead of a straight push, thus reducing the power required to move thesaid plate.` This reciprocating action also results in a better andsmoother surface on the'concrete as the hard the-machine slowlymovesforward, the gearing will be thrown into actiont to reciprocate theroller19. over the surfacel of the road. Preferably, the machine isadvanced about; onefoot while theroller moves entirely across the roadinone direction. vThe channel 15, at the forward side of the machine,will be disposed somewhat higher than the channel 15 at the rear sid-eof the machine so that the roller 19 will `have an upward inclinationforwardly. The` concrete layer is thus compressed to a lower level bythe successive movements of the roller thereacross. This compression isobtained Without vibration by the movement of the roller. isobjectionable and tends to produce a vertical displacement of the forms.Generally, the roller will be from1/4 of an inch to 1/2 inch higher atits forward end than at its rear end and said roller will be about tenSuch vibration feet in length. A compression of 1/20th to l/40th of aninch is thus obtained by each reciprocation of the roller. The roller isheld in position to give the exact crown desired by the channel members15. The compression 0f the concrete layer by the roller squeezes outthe'surplus moisture which flushes oif the road and this eliminates oneof the frequent causes of surface scaling and the formation ofdepressions by moisture standing on the surface. The action of theroller produces a smooth surface and also eliminates the short choppywaves often cased by machines having a reciprocating bar for screedingthe concrete. As already set forth, the roller can move out on theextensions to take care of extended widths of the roads at curves andother places s0 as to eliminate the use of a temporary false form. Whensuch wider ortions of the road are made the extensions- 1 and 72 will bebolted to the plate 70 and the end frames and wheels at the wide side ofthe road moved outwardly. The roller can then be traversed over theextended width as described, the length of the cha-in 20, of course,being correspondingly increased.

From the above description it is seen that applicant has provided a veryefficient machlne for surfacing roads. The machine is easil constructedfrom structural steel and can e quite easily and inexpensively made. Bythe use of the machine the labor and time necessary for building theconcrete road are greatly reduced and a more perfect and better road isobtained.

It will, of course, be understood, that various changes may be made inthe form, details and arrangement of the device without departing fromthe scope of applicants invention, which, generally stated, consists ina device capable of carrying out the objects above enumerated and suchas shown and described and defined in the appended claims.
